DETAILED DESCRIPTION OF THE EMBODIMENTS

Exemplary embodiments will be described in detail herein, and examples thereof are illustrated in the drawings. When the following description refers to the drawings, the same numbers in different drawings indicate the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations in accordance with the present disclosure. Rather, they are merely examples of apparatuses and methods in accordance with some aspects of the present disclosure as detailed in the appended claims.

As shown in FIG. 1, a display apparatus 1 may include a transparent screen 11 and a main screen 12, and the transparent screen 11 may realize a light-transmission function and a display function. A photosensitive component such as a camera and a distance sensor may be provided below the transparent screen 11.

Pixel circuits for pixels in the transparent screen 11 may be disposed outside the transparent screen 11, which may effectively prevent the pixel circuits for the pixels in the transparent screen 11 from affecting an imaging effect. However, if the pixel circuits for adjacent pixels in the transparent screen are far away from each other, an electrical difference may occur between the pixel circuits, resulting in non-uniform display.

The present disclosure provides an array substrate, a display panel and a display apparatus, which may improve the display uniformity in a transparent display region.

The first pixel circuits may be provided in the second display region, which can effectively increase the light transmittance of the first display region.

First pixel circuits for the first pixels with the same color in two of the display sub-regions in the first display region 21 adjacent to a central axis 27 of the first display region 21 are symmetrical with respect to the central axis 27 of the first display region 21. In an embodiment, as shown in FIG. 3, the display sub-regions 214 and 215 in the first display region 21 are two display sub-regions which are adjacent to the central axis 27 of the first display region 21, and the first pixel circuit 244 for the first pixels with the red color in the display sub-region 214 and the first pixel circuit 245 for the first pixels with the red color in the display sub-region 215 are symmetrical with respect to the central axis 27 of the first display region 21. In this way, the first pixel circuits for the first pixels with the same color in the two display sub-regions may be in a similar environment, thereby effectively avoiding a significant difference in display brightness caused by an electrical difference between the two first pixel circuits, and improving the uniformity of the display brightness.

In an embodiment, the N colors may include red, green, and blue colors. For example, the first pixel unit may include red, green, and blue first pixels, such that the first display region may display more colorful images.

In an embodiment, first pixel circuits for the first pixels with the same color in two of the display sub-regions in the first display region 21 symmetrical with respect to the central axis 27 may be symmetrical with respect to the central axis 27. As shown in FIG. 3, the display sub-region 211 and the display sub-region 218 are symmetrical with respect to the central axis 27, and the first pixel circuit 241 for the first pixels with the red color in the display sub-region 211 and the first pixel circuit 248 for the first pixels with the red color in the display sub-region 218 are symmetrical with respect to the central axis 27; the display sub-region 212 and the display sub-region 217 are symmetrical with respect to the central axis 27, and the first pixel circuit 242 for the first pixels with the red color in the display sub-region 212 and the first pixel circuit 247 for the first pixels with the red color in the display sub-region 217 are symmetrical with respect to the central axis 27; and the display sub-region 213 and the display sub-region 216 are symmetrical with respect to the central axis 27, and the first pixel circuit 243 for the first pixels with the red color in the display sub-region 213 and the first pixel circuit 246 for the first pixels with the red color in the display sub-region 216 are symmetrical with respect to the central axis 27. This may ensure that the first pixel circuits for the first pixels with the same color in the two display sub-regions in the first display region symmetrical with respect to the central axis are in a similar environment, such that the first pixels with the same color in the two display sub-regions have similar display brightness, allowing the display brightness of the first display region to be more uniform.

In an embodiment, the first pixel circuits for the first pixels with the same color in the adjacent display sub-regions on the same side of the central axis 27 of the first display region 21 are adjacent to each other. As shown in FIG. 3, the display sub-region 211 and the display sub-region 212 are located on the same side of the central axis 27 and adjacent to each other, and the first pixel circuit 241 for the first pixels with the red color in the display sub-region 211 and the first pixel circuit 242 for the first pixels with the red color in the display sub-region 212 are adjacent to each other. In this way, the adjacent display sub-regions may have similar display brightness, which is beneficial to more uniform display brightness.

Likewise, the display sub-regions 213 and 214 are adjacent to each other, and the first pixel circuits 243 and 244 for the first pixels with the same color in the display sub-regions 213 and 214 are adjacent to each other; the display sub-regions 215 and 216 are adjacent to each other, and the first pixel circuits 245 and 246 for the first pixels with the same color in the display sub-regions 215 and 216 are adjacent to each other; and/or the display sub-regions 217 and 218 are adjacent to each other, and the first pixel circuits 247 and 248 for the first pixels with the same color in the display sub-regions 217 and 218 are adjacent to each other.

This may effectively prevent the pixel circuits from occupying too much space due to a larger number of display sub-regions, allowing little difference in the brightness between the adjacent display sub-regions. Accordingly, the first display region may have more uniform display brightness, and the pixel circuits for the pixels in the first display region may occupy less space.

In an embodiment, the second display region 22 may include a first sub-display region 221 and a second sub-display region 222.

The first pixel circuits 241-248 may be located in an area of the first sub-display region 221 close to the first display region 21. For example, the second pixel circuits 25 may be closely arranged in an area of the first sub-display region 221 away from the first display region 21, such that there may be enough space in the first sub-display region 221 for arranging the first pixel circuits 241-248, thereby facilitating the wiring and reducing the process difficulty.

The shape of the first pattern unit and/or the second pattern unit such as a circle, an ellipse, a dumbbell shape, and a gourd shape may change a periodic structure that produces diffraction, that is, the shape may change a distribution of diffraction fields, and thus reduce the diffraction. This may ensure that images captured by a camera provided below the first display region have higher definition.
